This is not a normal job.

Hub.xyz is a Y Combinator P26 company. Our batch starts March 31. Demo Day is June 16. This is only couple weeks from now.

YC has funded over 5,000 companies. 90+ became billion-dollar companies: Stripe. Airbnb. Coinbase. Dropbox. Reddit. Twitch. Brex. Deel. Rippling.

That is multiple times the rate of any other venture-backed seed-stage startup on the planet. YC companies have a combined valuation north of $600 billion.

You are applying to be a founding engineer at one of these companies. The equity you will potentially earn here could change your life. That depends entirely on what you build in the next 97 days.

If you are looking for work-life balance, a predictable schedule, or a manager who tells you what to do, close this page now. No hard feelings.

If you are still reading, let's go.

🌐 About Hub

Hub is a distributed AI data infrastructure company. We provide real-world training data to AI companies through a global network of 500,000+ contributors across 150+ countries and 100+ languages.

We own the full end-to-end pipeline: collection, automated processing, human-in-the-loop QA, and delivery. Our clients are leading AI labs and top-tier technology companies who need original, hard-to-access multimodal data, audio, image, and video — that doesn't exist on the public web.

The vision: make real-world data collection for AI as simple as an API call.

🎯 Who We're Looking For

This role is not for everyone. We're a small team moving at YC batch pace. The work is real, the stakes are high, and there's no time to manage people.

• Ownership over excuses. You see a problem, you fix it, you document it. You don't wait to be told.
• Speed without sloppiness. You ship fast and you ship clean. You know when to cut and when not to.
• Async-first mindset. You communicate proactively, write clearly, and never become a blocker because you're offline.
• Intellectually honest. You rate yourself accurately. You say "I don't know" and then go find out.
• AI-fluent. You don't just use AI tools, you build with them and on top of them. You've integrated LLM APIs into production systems, you know when to trust model output and when to verify, and you're constantly pushing what's possible with AI-assisted engineering. If you're not already shipping code with Cursor or Copilot daily, you're behind.
• Builder identity. You have things you've built that you're proud of — side projects, open source, internal tools. You build because you can't help it.
• Low ego, high standards. You take feedback without flinching. You give it without politics. You care about the work, not the credit.

<aside> ⚠️

If your primary motivation is salary, stability, or job title, this is the wrong fit. If you want to build infrastructure used by the world's leading AI companies and come out the other side with equity and a track record that speaks for itself, keep reading.
